ASoC: blackfin: Switch bf5xx-ad193x from bf5xx-tdm to bf5xx-i2s
The bf5xx-i2s driver now has support for TDM mode and the bf5xx-tdm driver is going to be removed soon, so switch the driver over to bf5xx-i2s. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
